COMBINED LEVEL AIil'D PLUHB.

Application fled June 8 1925. Serial Io. 85,888;

This invention relates to leveling instruments of the class which embodies liquid,

containers to indicate the level, plumb and other positions.

The ob'ect of the invention is to provide a simple evice of this charater whichis ve light to handle, pack and carr and whic may indicate the relations tot e horizontal or vertical in any ordinary position in which it may be laid or set.

With the foregoing and other objects inview which will appear as the description roceeds, the invention resides in the comination and-arrangement of arts and in 16 the details of construction, it ing understood that changes in the precise embodiment of the invention herein disclosed may be made within the scope of what is claimed without departing from the spirit of the in-' vention.

In the accompanying drawings Figure 1 represents a side elevation of the instrument embodying this invention.

Fig. 2. is an enlarged detail side eleva- Fig. 3 is a section taken on the line 3-3 of Fig. 2, and

r Fig. 4 is atransverse section taken on the line 4-4 of Fig. 1.

The level constituting this invention has a body 1 preferably stamped out of sheet metal andrsubstantially I-shaped in cross section similar to an I beam.

ortion or web 2 of the level.

The central is longitudinal y corrugatedor crimped and is preferably rovided with a plurality of ii hten the structure and pro vide means for anging it up.

Arranged between the openings 3 are spe- .lio-cially" formed openings 4 adapted to hold...

vessels 5 for containing the leveling liquid. 6 and "'7 represent faces of the instrument and thej'face 7 has a longitudinally extending corrugationor depression 8 to stiffen and reinforce it, the face 6 being made smooth throughout. Two angular portions 9 unite thaweb 2: with the faces 6 and 7 at one of their longitudinal edges. Wedge-shaped d1 k blocks 10 are fastened and fill the space between the face 6 and the angular portion 9 to stiffen the level and render it more symmetric andmore massive in appearance.

The vessels 5 are here shown constructed substantially rectangular in form of translucent material and are filled with alcohol or other suitable li uid except for the vacuum bubbles indicate at 5".

Each container '5 is equipped with recesses 11 preferably located in the corners thereof and adapted to receive metal lips struck out of the body of the level some of which are located on one side of the level and some on the other and are designed to hold the container 5 in operative position. A plurali of marksC are formed on the surfaces 0 thecontainer at the edges of the bubbles at the level, plumb and other positions of the instrument.

The container 5 may be made to have six to cause it to gradually sink in the fluid and thus leave the vacuum bubble 5' with ample room to seat itself at the highest point in the container when the instrument'is used.

A channel section ring 14 is set tightl in acircular aperture 15 formed in the web of the level-'and this ring is equipped quadrant degrees 16 marked on t e outer aces of the channel and corresponding notches 17 extend transversely across the inner face of the channel ring.

A disk-shaped member 18 is mounted within the ring 14 and is equipped with a peri heral flange 19 on the outer edge of whic are formed a plurality of outward] and. radially extendingl lugs 20. This dis 18 also-is equipped wit a plurality of small outwardly formed ont e edges of the periphery of the s The disk 18 has centrall mounted therein one of the containers 5 w ch is secured in a manner similar to that hereinbefore described.

with i ro ecting indicator points 21 The indicator points 21 are preferably set. 1

at the quadrant degrees of the circle and the container is set with its outer four faces square with the indicators so that normal] the bubbles in any of these outer faces wil be in line with an indicator.

A narrow leaf spring 22 is fitted concentrically within and on the inner face of the periphery or rim of the disk 18 and is se-- cured at one end to said disk b rivets or otherwise; A block 23 is carried by the free ends of the spring 22 which extends through an opening 24 in the flange 19 of the disk. This block 23 has teeth or serrations on its outer face which cooperate with the notches or teeth 17 of the ring. 14. This meshing of the block with the ring 14 operates to hold the disk 18 with its container 5 and indicator points at any desired marked degree of angle.

It is understood of course that in order to easily adjust the disk 18 the block 23 may be disengaged from the ring 14, a finger grip 25 being provided for this purpose.

The container 5 being six faced and convex in form is sufficiently strong that no guards are found necessary over it thus afis obtained and the construction of which adapts it to be very light to facilitate handlin lut is claimed is In a device of the character described, a body portion having an opening extending therethrough, a ring member having raduations formed thereon positioned wit ill] the opening, a disk-like member having a central opening adjustabl secured to said ring member, a hollow bo y portion rcinovably supported within the opening of the disklike member, said hollow body portion containing a fluid, a bubble, and a movable solid body within the hollow body portion, and means for adjusting the disk-like body portion with respect to the ring member.

In testimony that I claim the foregoing as my own, I have hereto aflixed my signature.
